Voltage Test
1. Place the red (+) probe of a multimeter set at Volts DC, 20 volt range, on the positive (+) cable and place
the black (–) probe on the negative (–) post of the battery and take a voltage reading. If it shows less than
12.4 volts, or if the lowest specific gravity reading from the hydrometer test is less than 1.225, recharge
the battery. If battery voltage is greater than 12.4 volts and specific gravity is greater than 1.225, the prob-
lem is not with the battery. If the battery does not reach 12.4 volts, or if the specific gravity of a cell is still
less than 1.225 after charging, replace the battery.
See following NOTE.
NOTE:
A fully charged battery that is in good condition should have a specific gravity of at least 1.225 in
all cells, and the difference in the specific gravity of any two cells should be less than 50 points.
Open circuit voltage should be at least 12.4 volts.
Load Test
1. Connect a 160-ampere load tester to the battery posts.
2. Turn the switch on the load tester to the ON position.
3. Read the battery voltage after the load tester has been turned ON for 15 seconds. Compare the battery’s
voltage reading with the table below. Make sure you have the correct ambient temperature.
4. If the battery is found to be good, or if the electrical problem continues after the battery has been replaced
with a good one, test the electrical circuits.
TEST PROCEDURE 2 – FUSE
See General Warning on page 1-1.
The fuse (red 10 amp) is located in the electrical component box.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL posi-
tion. Chock the wheels.
2. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-2.
3. Remove the cover on the electrical component box.
4. Check that wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
5. Remove fuse to be tested from the fuse block.
See Fuse Removal, Section 13, Page 13-16.
The red
10 amp fuse protects the solenoid for the starter (cranking) circuit. The 20 amp fuse at the yellow wire
connection protects the headlights.
